Technical field
The utility model relates to air-to-water heat pump, particularly full adverse current air-to-water heat pump.
Background technology
In heat exchanger, heat transfer temperature difference affects the size of heat output, from heat transfer formula Q=KA (Δ Tm), can learn, the Δ Tm Q that more conducts heat is larger, and in the heat exchangers such as adverse current, following current, distributary, the mean temperature difference of contra-flow heat exchanger is maximum, and heat exchange efficiency is the highest.
Before the present utility model, tradition air-to-water heat pump just carries out counter-flow designs for single operating mode, can only guarantee countercurrent flow under single operating mode, can not meet refrigeration and heating condition is all countercurrent flow simultaneously, so often can not all keep higher heat exchange efficiency when refrigeration and heating condition, efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, develops full adverse current air-to-water heat pump.
Technical solutions of the utility model are:
Full adverse current air-to-water heat pump, its technical characteristics is that cross valve connects respectively compressor, gas-liquid separator, water-side heat, heat and goes out check valve, coldly enters check valve, compressor connects gas-liquid separator, coldly enter that check valve connects air side heat exchanger respectively, heat is entered check valve, heat is entered check valve and is connected respectively expansion valve, coldly goes out check valve, heat goes out check valve and connects respectively air side heat exchanger, coldly goes out check valve, and expansion valve connects water-side heat.
Describedly coldly enter check valve, coldly go out check valve, heat and enter check valve, heat to go out check valve be check valve or magnetic valve.
Described air side heat exchanger is finned heat exchanger or micro-channel heat exchanger.
Described water-side heat is a kind of in case tube heat exchanger or plate type heat exchanger or double-tube heat exchanger or tube-sheet heat exchanger.
Advantage of the present utility model have following some:
1. heat exchange efficiency is high: utilize full adverse current loop, make in wind side refrigeration and heat can countercurrent flow, heat transfer temperature difference is larger, good effect of heat exchange.
2. frosting in winter is delayed and is lacked: utilize full adverse current loop, can promote evaporating temperature.The lifting of evaporating temperature is postponed heat pamp and is reduced frosting degree, so the whole frosting of unit is delayed especially and lacked.
3. improve heating capacity and expand heating operation scope: because utilize the flow direction of refrigerant in air side heat exchanger to become adverse current to improve the heat exchange efficiency of refrigerant and air with environment air intake direction, improved evaporating temperature, refrigerant mass flow increases, heating capacity increases, Energy Efficiency Ratio promotes, delivery temperature reduces, can heating operation under lower environment temperature.
Other concrete advantages of the present utility model and effect will go on to say below.
Accompanying drawing explanation
Fig. 1---the utility model structural principle schematic diagram.
In figure, each label represents that corresponding component names is as follows:
Gas-liquid separator 1, cross valve 2, heat go out check valve 3, coldly enter check valve 4, air side heat exchanger 5, coldly go out check valve 6, water-side heat 7, heat and enter check valve 8, expansion valve 9, compressor 10, environment air intake 11.
The specific embodiment
Technical thought of the present utility model is:
Utilize refrigerant flow direction in air side heat exchanger to become adverse current to improve the heat exchange efficiency of refrigerant and air with air-flow direction.
As shown in Figure 1:
Water-side heat 7 connects cross valve 2 one end, cross valve 2 also connects respectively compressor 10, gas-liquid separator 1, heat and goes out check valve 3, coldly enters check valve 4, compressor 10 is connected to gas-liquid separator 1, heat is entered check valve 8 and is connected expansion valve 9, coldly enter that check valve 4 connects respectively air side heat exchanger 5, heat is entered check valve 8, air side heat exchanger 5 connect coldly go out check valve 6, heat goes out check valve 3, coldly go out check valve 6 and connect expansion valves 9, expansion valve 9 connects water-side heat 7, and air side heat exchanger 5 sides are environment air intakes 11.
The explanation of the utility model application process:
Under cooling condition, after refrigerant evaporates in water-side heat 7, by cross valve 2, enter and in gas-liquid separator 1, carry out gas-liquid separation, then enter in compressor 10 and compress, again successively by cross valve 2 with coldly enter check valve 4 and enter air side heat exchanger 5, after refrigerant condensation, through cold, go out check valve 6 and enter in expansion valve 9 and expand, then enter water-side heat 7, form a kind of refrigeration cycle.
In this process, refrigerant and air heat-exchange occur in air side heat exchanger 5, and flow direction and environment air intake 11 directions of refrigerant in air side heat exchanger 5 form adverse current, so heat exchange efficiency is high, condensation temperature reduces, and refrigerating capacity increases, and Energy Efficiency Ratio improves.
Under heating condition, water-side heat 7 serves as the effect of condenser, and air side heat exchanger 5 serves as the effect of evaporimeter.After refrigerant evaporates in air side heat exchanger 5, through overheated, go out check valve 3 successively, enter and in gas-liquid separator 1, carry out gas-liquid separation with cross valve 2, then enter in compressor 10 and compress, by cross valve 2, enter and in water-side heat 7, carry out condensation again, then enter in expansion valve 9 and to expand, by heat, enter check valve 8 and get back to and in air side heat exchanger 5, form one and heat circulation.
In this process, refrigerant and air heat-exchange also occur in air side heat exchanger 5, and flow direction and environment air intake 11 directions of refrigerant in air side heat exchanger 5 form adverse current, so heat exchange efficiency is high, evaporating temperature improves, and heating capacity increases, and Energy Efficiency Ratio improves.
In sum, in the utility model, no matter at cooling condition or heating condition, refrigerant in air side heat exchanger 5 flow direction all become adverse current with environment air intake 11 directions, so the temperature difference of heat exchange is large, heat exchange is more abundant, heat exchange amount is larger, and heat exchange efficiency is high.During refrigeration, refrigerating capacity increases, and condensation temperature reduces, and Energy Efficiency Ratio improves; While heating, evaporating temperature improves, and heating capacity increases, and Energy Efficiency Ratio improves.
